Specification of Letters Patent.

Patented July llfi jld.

Application filed August 15, 1917. Serial No. 186,342.

To all whom it may concern Be it known that I, JOHN Sormnna citizen of the United States, residing at Tolyoke, in the. county of Hampden and State of lllassachusetts, have invented cer tain new and useful Improvements in Loose- Leaf Ledgers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in a loose leaf binder and particularly to'a loose leaf ledger of that type known as sectional ledgers which are used by book-keepers in department stores and other business establishments.

Among other aims and objects, the present invention resides in an improved and reinforced mounting for the telescopic post parts of the binder which is simple and easy of assemblage.

Further, the invention resides in an i1nproved hinged knuckle construction and mounting between the cover and the back section which facilitates the assemblage and eliminates the necessity of attaching rivets or other extra fasteners.

In the drawings:

Figure 1 is a fragmentary plan of a loose leaf ledger in its opened position;

Fig. 2 is an end View thereof;

Fig. 3 is a transverse section on line 33 of Fig. 1;

Fig. 4: is a transverse section through the ledger back, showing the manner of mounting a hinge knuckle thereto;

Fig. 5 is a detailed section thereof on line 99 of Fig. 4;

Fig. 6 illustrates one step in the opera tion of mounting the hinge knuckles;

Fig. 7 is a plan of the blank from which the hinge knuckles are constructed;

Fig. 8 is a perspective of a further form of ledger back;

Fig. 9 discloses a modification of the hinge knuckle; and,

Fig. 10 is a perspective view of the modified hinge knuckle.

Referring in greater particularity to the drawings, the numerals l designate the pair of cooperating back sections of the loose leaf ledger, each of which comprises an l.shaped bar having its corner or angle col' cavo-convexcross section. The base and concavo-convex part are formed at intervals with registering apertures-5. Both the male and female parts of the binder posts 6 have flared heads and are inserted inwardly through the apertures of the base and concavo-convex portion 4, said flared heads seating in the base apertures and being securely retained in operative position by the j cheek plates 7.

In Fig. 8, a modified showing is disclosed wherein the l -sh aped bar has the free edge of its base turned backwardly in opposing and parallel relation thereto, as at 8, and is likewise formed with apertures 5 registering with apertures in the base, as in the pre ferred form.

In either form the post parts are securely held against dislodgment and receive a double reinforcement against lateral strain at spaced points where said posts pass through the base and the overlying portions 4 and 8.

The hinge knuckles which pivotally connect the covers 9 to the back sections are each formed from an I-shaped blank 10 which is bent on a transverse center line to provide a pintle-rcceiving socket 11, a neck portion 12 and a comparatively wide support or base 13, which broadens out on opposite sides from the neck to provide side single thicknessof metal, the free end of i the reduced neck 17 being rolled into apintle socket 18 whereas the free edge of the base 19 is bent at right angles to provide a sustaining spacer flange 20 which serves to eliminate all looseness in the mounting of the hinge knuckle after the concavo-eonvex portion has been bent down.

The neck portions'of the hinge knuckles are curved outwardly and the sockets are preferably received in cut-outs or recesses 22 in the cover, a hinge pin 23 being passed through said sockets in an obvious manner.

It is therefore obvious that the several parts of the binder may economically and facilely be constructed Without the employment of additional parts, as rivets for the hinge knuckles Further, the sheet transferring devices improve the method of transferring or turning leaves.

What is claimed is:

1. In a loose leaf binder, a pair of opposing members having corresponding free edges bent backwardly upon themselves in spaced relation and provided with apertures at the bends of said free edges, and hinge knuckles secured beneath the bent free edges and extending through the apertures of said bars.

2. In a loose leaf binder, a pair of oppo. ing members having corresponding free edges bent backwardly upon themselves in spaced relation and provided with apertures at the bends of said free edges, and hinge knuckles secured beneath the bent free edges and extending through the apertures of said bars, each knuckle comprising a pintle-receiving socket supported by a neck portion from a comparatively Wide base extending from opposite sides of the neck to provide shoulders, the socket and neck being inserted through the respective aperture to seat the shoulders against the inner side of the bend of said bar.

3. In a loose leaf binder, apair of opposing members having corresponding free edges bent backwardly upon themselves in spaced relation and provided with apertures at the bends of said free edges, hinge knuckles secured beneath the bent free edges and extending through the apertures of said bars, each knuckle comprising a pintle-receiving socket supported by a neck portion from a comparatively Wide base extending from opposite sides, of the'neck to provide Copies of this patent may be obtained for shoulders, the socket and neck being inserted through the respective aperture to seat the shoulders against the inner side of the bend of said bar, and the backvardly bent free edge being turned down upon the latter over the free edge of the base.

4. In a loose leaf binder, a pair of opposing members having corresponding free edges bent backwardly upon themselves in spaced relation and provided with apertures at the bends of said free edges, hinge knuckles secured beneath the bent free edges and extending through the apertures of said bars, each knuckle comprising a pintle-receiving socket supported by a neck portion from a comparatively wide base extending from opposite sides of the neck to provide shoulders,,the socket and neck being inserted through the respective aperture to seat the shoulders against the inner side of the bend of said bar, and the backwardly bent free edge being turned down upon the latter over the free ends of the base, said necks being curved outwardly.

5. In a loose leaf binder, a pair of opposing members having corresponding free edges bent backwardly upon themselves in spaced relation and provided with a iertures at the bends of said free edges, hinge knuckles secured beneath the bent free edges and extending through the apertures of said bars, each knuckle comprising a pintle-receiving socket supported by a neck portion from a comparatively wide base extending from opposite sides of the neck to provide shoulders, the socket and neck being inserted through the respective aperture to seat the shoulders against the inner side of the bend of said bar, said necks being curved outwardly, covers having edge recesses for receiving the sockets of the hinge knuckles and pivot pins passed through the sockets and covers for hinging the latter to the bars.

In testimony whereof I al'lix my signature.

JOHN SCHADE.
